Cleveland - #28 135° Cobalt Jobber Drill
Item #: 02950640
Brand: Cleveland
Model #: C11428
Features and Benefits
Cobalt is harder than high speed steel and provides better wear resistance. It is commonly used on high tensile alloys.
Titanium Aluminum Nitride (TiAlN) has a higher hardness and oxidation temperature versus TiN and TiCN. As a result, it is particularly advantageous for higher speed operations in a variety of steel machining applications.
Parabolic flutes are constructed with a wider flute shape for increased chip flow.
